Connect file storage to a dedicated server
The file storage and the dedicated server are always in different pools, so to connect the file storage to the dedicated server, you must configure private network connectivity at the L3 level through a global router.
Some configurations of Chipcore Line dedicated servers cannot be added to the global router network because they do not have a port to connect to the private network. The availability of the private network port can be checked in the control panel: click Products in the top menu and select Dedicated Servers → Servers → Server → Server page → Ports tab.
-
Connect the network and subnet to the global router up to the VLAN of the dedicated server.
-
Connect the network and subnet for the file storage to the global router.
See an example of connecting file storage to a dedicated server.
The instructions describe connection examples for dedicated servers with Ubuntu, Debian, CentOS and Windows operating systems. Instructions for servers with VMware ESXi, Proxmox and FreeNAS operating systems — in the Selectel Selectel File Storage blog article.
Example of connecting file storage to a dedicated server
For example, you want to connect file storage in the ru-2 pool to a dedicated server in the SPB-2 pool.
-
Create a global router.
-
Connect two private subnets to the global router —
192.168.0.0/29
with gateway192.168.0.1
for the SPB-2 pool and172.16.0.0/29
with gateway172.16.0.1
for the ru-2 pool. -
Assign an address from the
192.168.0.0/29
subnet to a dedicated server, such as192.168.0.2
. -
Write a route on the dedicated server in the SPB-2 pool — to subnet
172.16.0.0/29
via gateway192.168.0.1
. -
Create a file store on the
172.16.0.0/29.
subnet. -
Mount the file storage to a dedicated server.


1. Create a global router
- In the Control Panel, on the top menu, click Products and select Global Router.
- Click Create router. Each account has a limit of five global routers.
- Enter the name of the router.
- Click Create.
- If the router is created with ERROR status or hangs in one of the statuses, create a ticket.
2. Connect the network and subnet to the router to the VLAN of the dedicated server
You can connect a new network to the router or an existing network if it is not already connected to any of the account's global routers.
-
In the Control Panel, on the top menu, click Products and select Global Router.
-
Open the router page → Networks tab.
-
Click Create Network.
-
Enter a network name, this will only be used in the control panel.
-
Select a Servers and Hardware service.
-
Select a pool.
-
Select VLAN. If you want to create a network up to the internal segment (Q-in-Q), specify its tag, a number from 2 to 4094. If there is already a network up to the VLAN, be sure to specify the Q-in-Q segment of this VLAN.
-
Enter the subnet name — this will only be used in the control panel.
-
Enter the CIDR — IP address and private subnet mask. You can enter a new subnet or an existing private subnet of the server if it is not already added to any of the global routers in the account. The subnet must meet the conditions:
- belong to the RFC 1918 private address range:
10.0.0.0/8
,172.16.0.0/12
, or192.168.0.0/16;
; - have a size of at least /29, as three addresses will be occupied by Selectel network equipment;
- Do not overlap with other subnets added to this router: The IP addresses of each subnet on the router must not overlap with the IP addresses of other subnets on the router;
- If Managed Kubernetes nodes are included in the global router network, the subnet must not overlap with the ranges
10.250.0.0/16
,10.10.0.0/16
and10.96.0.0/12
. These subnets participate in the internal addressing of Managed Kubernetes and their use can cause conflicts in the global router network.
- belong to the RFC 1918 private address range:
-
If you specified the Q-in-Q tag, make sure to configure Q-in-Q. When configuring, use the subnet you specified in step 10.
-
Enter the gateway IP or leave the first address from the subnet assigned by default. Do not assign this address to your devices to avoid disrupting the network.
-
Enter service IPs or leave the last addresses from the subnet assigned by default. Do not assign these addresses to your devices to avoid disrupting the network.
-
Click Create Network.
-
Optional: Check the network topology on the global router. In the control panel, from the top menu, click Products → Global Router → Router page → Network Map.
3. Connect a network and subnet to the router for file storage
If the cloud platform network is connected to a global router, you can only manage it on the global router page.
You need to connect the network and subnet to the global router up to the project and cloud platform pool where the file storage will be created in the future.
You can connect a new network to the router or an existing network if it is not already connected to any of the account's global routers.

; - have a size of at least /29, as three addresses will be occupied by Selectel network equipment;
- Do not overlap with other subnets added to this router: The IP addresses of each subnet on the router must not overlap with the IP addresses of other subnets on the router;
- If Managed Kubernetes nodes are included in the global router network, the subnet must not overlap with the ranges
10.250.0.0/16
,10.10.0.0/16
and10.96.0.0/12
. These subnets participate in the internal addressing of Managed Kubernetes and their use may cause conflicts in the global router network.
- belong to the RFC 1918 private address range:
-
Enter the gateway IP or leave the first address from the subnet assigned by default. Do not assign this address to your devices to avoid disrupting the network.
-
Enter service IPs or leave the last addresses from the subnet assigned by default. Do not assign these addresses to your devices to avoid disrupting the network.

-
Optional: Check the network topology on the global router. In the control panel, from the top menu, click Products → Global Router → Router Page → Network Map.
-
Check that the network has not yet been added to any of the account's global routers. In the Control Panel, in the top menu, click Products → Cloud Servers → Network → Private Networks tab → check that there is no Global Router tag in the network card.
-
Verify that the subnet meets the conditions:
- belongs to the RFC 1918 private address range:
10.0.0.0/8
,172.16.0.0/12
, or192.168.0.0/16;
; - is at least /29, as three addresses will be occupied by Selectel network equipment;
- does not overlap with other subnets added to this router: the IP addresses of each subnet on the router must not overlap with the IP addresses of other subnets on the router;
- If Managed Kubernetes nodes are included in the global router network, the subnet must not overlap with the ranges
10.250.0.0/16
,10.10.0.0/16
and10.96.0.0/12
. These subnets participate in the internal addressing of Managed Kubernetes and their use may cause conflicts in the global router network.
- belongs to the RFC 1918 private address range:
-
In the Control panel, on the top menu, click Products and select Cloud Servers.
-
Go to Network → Private Networks tab.
-
From the menu of the network, select Connect to Global Router.
-
Select the global router.
-
For each of the network subnets, enter the IP address that will be assigned to the router, or leave the first available address from the subnet assigned by default. Do not assign this address to your devices to avoid disrupting the network. The last two free subnet addresses will be reserved as service addresses.
-
Click Connect. Do not close the window until you see a message that the network is connected. After that, in the Control Panel:
- The network will appear in the Selectel Global Router section of the router page of the router you connected it to. You can view it in the control panel: from the top menu, click Products → Global Router → Router page;
- the network will have the Global Router tag. You can view it in the control panel: in the top menu, click Products → Cloud Servers → Cloud Server page → Network section → Network card.
